....on the 27 lines on the generic cubic surface over the purely transcendental field C(a 1 , a 20 ) is W (E 6 ) this follows from [Tod35] so the same is true for the generic cubic surface over Q(a 1 , a 20 ) and it then follows by Hilbert irreducibility (see 9. 2 and 13 of [Ser97] that the same holds for a density 1 set of cubic surfaces over Q. Such cubic surfaces, under Conjecture 3.2, satisfy the Hasse principle as desired. Remark 3.5. For n large compared to d, the conclusion of Proposition 3.4 can be proved unconditionally by using the circle method. Part (ii) ....

....before. Instead of counting polynomials 3 with bounded coe#cients, we let N tot (H) be the number of hypersurfaces whose corresponding point in P (k) has (exponential) Weil height H. There is no longer an exact formula for N tot (H) but its asymptotics are given by Schanuel s Theorem (see [Ser97, 2.5] for an exposition) We define N(H) and N loc (H) in a similar way. In the special case k = Q, these definitions do not agree with the earlier ones (since we are now counting hypersurfaces instead of polynomials) but the ratios of interest have the same limit, by Remark 2.1(2) The ....

....e corresponds under # to p #e 2# Z p , and is hence a subgroup. b) The number log d n is the logarithmic height h(nP ) except that in the sum defining the height, the terms corresponding to places in S bad # # have been omitted. A standard diophantine approximation result (see Section 7. 4 of [Ser97]) implies that each such term contributes at most a fraction o(1) of the height, as n # #. If h is the canonical height, then h(nP ) h(nP ) O(1) h(P )n O(1) Take c = h(P ) which is positive, since P is not torsion. Remark 3.2. The bottom of p. 306 in [Aya92] relates the ....

....same. These results may viewed as elliptic analogues of Zsigmondy s Theorem: see [Eve02] 4. Definition of T 1 and T 2 For each prime number #, let a # be the smallest a such that d # a 1. By Lemma 3.1(b) a # exists, and a # = 1 for all # outside a finite set L of primes. Baker s method [Ser97, Chapter 8] lets us compute the finite set E # (Z[S 1 ] so the set L and the values a # for # L are computable. Let p # = maxS # a where a = a # . For primes # and m (possibly equal) Lemma 3.4 lets us define p #m = max (S #m Sm ) when max #, m is su#ciently large. Let # 1 # 2 . be ....

....K of genus 1. Fix a place v of K. Let # be a nonconstant rational function on X. Let P 1 , P 2 , be a sequence of distinct points in X(K) For su#ciently large m, Pm is not a pole of #, so z m : #(Pm ) belongs to K. Then lim m## log #z v h(z m ) 0. Proof. See Section 7. 4 of [Ser97]. Lemma 8. The following holds if r is su#ciently large: If P 1, 0, 1 , then log NK Q den(x(mP ) 9 10 log NK Q den(x(P ) 0; in particular den(x(mP ) den(x(P ) and den(x(P ) 1) Proof. Let P 1 be a generator of rE(K) The theory of the canonical height in ....

....of Q[x] and that deg f 2. Fix q Q # such that q 1. Then the number of solutions (m, n) to f(m) qf(n) satisfying 1 m,n B is o(B) as B ##. Proof. Since f(m) has constant sign for large positive m, the result is trivial if q 0. Therefore assume q 0. Theorem 2 in Chapter 13 of [Ser97] implies that the number of such solutions on each irreducible component of the curve f(m) qf(n) 0 in the (m, n) plane over Q is O(B 1 2 log B) unless some component is a line. If there is a line, it cannot be of the form n = # for any # Q, so it would have an equation m = #n # for some ....
